Key takeaways
- The SCUM developer enabled Proton support for multiplayer on Linux in update v1.3.6.0.177121.
- Steam Deck and Steam Machine are named in the announcement as supported devices.
- Only single-player worked on Linux before, and players relied on workarounds for multiplayer.
- SteamOS and Linux systems still show SCUM as Unsupported on Steam.
- The game switched from Easy Anti-Cheat to BattlEye at some point before the change.
What the update changes
The open-world survival game SCUM now officially supports joining multiplayer servers through Proton on Linux, including Steam Deck and Steam Machine. The developer announced the change in update v1.3.6.0.177121.
Before the update, only single-player worked on Linux, and some players found workarounds to reach multiplayer servers. The developer acknowledged that history in its announcement: some players had already found ways to get multiplayer running, and the new support makes that official.
SCUM was released in June 2025. At some point it moved from Easy Anti-Cheat to BattlEye, according to GamingOnLinux.
Steam status still says unsupported
The change has not yet reached the Steam listing. SCUM is currently listed as Unsupported across SteamOS and Linux systems, and GamingOnLinux expects Valve to re-test it.
The site notes that Rust remains blocked on Linux, with the possibility that Facepunch enables it once Easy Anti-Cheat v2 arrives. SCUM's new status is tracked on GamingOnLinux's anti-cheat page.
GamingOnLinux also reports SCUM at 70% off on Indiegala for a limited period.
